8.In L-R circuit, the time constant is given by:

9.According to Faradays law, the total charge induced in a conductor that is moved in a magnetic field depends upon:

10.If a current of 3 A flowing in the primary coil is reduced to zero in 0.01 s then the induced emf in the secondary coil is 1500 V, the mutual inductance between the two coils is:
